Abstract:
The results of a for a bipolarized X-band antenna array is presented. A special feature of the design is the use of a milled base, which makes it possible to reduce the mutual influence between the microstrip lines of the feed network and thereby achieve the required a decreasing to the edges amplitude distribution in the antenna surface to reduce the level of the side lobes. Experimental studies on the layout of a common-mode, bipolarized antenna array with dimensions of $3\lambda_0\times 6.7 \lambda_0$ (where $\lambda_0$ corresponds to the center frequency of the operational range) have shown a relative operational frequency band of 12%, with a standing wave ratio (SWR) $<$ 2 and a decoupling between polarization channels of at least -27 dB. Side lobe levels in orthogonal planes do not exceed -18 dB.
Keywords:antenna array, bipolarized, side lobe level, X-band, decreasing amplitude distribution.
